What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

There may be many more satellite galaxies in the Milky Way than have been observed, according to new Durham University ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite ...

Researchers may have found our galaxy's missing companions, further bolstering science's most widely accepted cosmological ...

Astrophysicists suggest our galaxy may lie inside a "cosmic void" - offering a new explanation for the universe’s conflicting ...

The Lambda Cold Dark Matter model suggests that 68 percent of the universe is made up of dark energy. But a new study has questioned whether dark energy exists, citing simulations that found that ...

What this CDM is, we have no idea. Furthermore, the model incorporates a cosmological constant (denoted by the Greek capital letter Lambda), which is permitted by Einstein’s theory, but what it ...

New research suggests that a troubling disparity in the rate of expansion of the universe, known as the Hubble constant, may arise from the fact Earth sits in a vast underdense region of the ...

The Lambda CDM model has worked quite well for years, but now observations clearly are pointing to a problem that needs to be solved, and it appears the problem lies with the model," Pesce said.

Plugging these into the Lambda-CDM model spat out a Hubble constant of roughly 46,200 mph per million light-years, or roughly 67 kilometers per second per megaparsec. (A megaparsec is 3.26 million ...
